چکیده
مواد جدید مقاوم در برابر زلزله به دلیل پتانسیل کاهش تغییر مکان باقیمانده پس از زلزله و در نتیجه کاهش هزینه‌های نگهداری، مورد توجه جامعه علمی قرار گرفته‌اند. مواد و فناوری‌های هوشمند باعث بهبود پاسخ لرزه‌ای ساختمان‌های بتن‌آرمه شده‌اند، اما تأثیر این پیشرفت‌ها بر مسائلی که پس از زلزله در دیوارهای برشی جفت‌شده بتن‌آرمه ایجاد می‌شود، هنوز مورد بررسی قرار نگرفته است. این تحقیق عملکرد لرزه‌ای دیوارهای جفت‌شده بتن‌آرمه را که با میلگردهای سوپر الاستیک حافظه‌دار شکلی نیکل تیتانیوم، آلیاژ های حافظه دار مبتنی بر آهن و آلیاژ های حافظه دار مبتنی بر مس در نواحی مرزی تقویت شده‌اند، مورد بررسی قرار می‌دهد. به عنوان بخشی از مطالعه موردی، سه سیستم دیوار جفت‌شده بتن‌آرمه با چهار، هشت و دوازده طبقه در نظر گرفته شد. بالاترین مقادیر بحرانی برای نسبت تغییر مکان نسبی طبقاتی و تغییر مکان نسبی باقیمانده طبقاتی از طریق نرم‌افزار اپنسیس به دست آمد. طبق نتایج، هر زمان که نگرانی‌های مربوط به امور پسا لرزه برجسته می‌شود، تغییر مکان نسبی پسماند به طور قابل توجهی کاهش می‌یابد. مطابق با یافته‌ها، در میان کل انواع آلیاژ های حافظه دار به کار رفته در این تحقیق، دیوار برشی جفت‌شده بتن‌آرمه مبتنی بر مس نتایج بهتری را در مورد تغییر مکان نسبی باقیمانده نشان داده و عملکرد مناسبی را در رابطه با اثر بازیابی ارائه می‌دهد. در نتیجه، به طور کلی توصیه می‌شود از آلیاژ های حافظه دار مبتنی بر مس در مناطق درگیر زلزله که در معرض حرکات شدید زمین قرار دارند، استفاده شود.

چکیده English

Recent advancements in earthquake-resistant materials have garnered significant attention from scholars due to their potential to mitigate seismic residual displacements and subsequently reduce maintenance costs. While novel materials and technologies have demonstrated their effectiveness in enhancing the seismic response of reinforced concrete (RC) buildings, their impact on post-earthquake challenges specific to RC-coupled walls remains unexplored. This study examines the seismic performance of RC-coupled walls reinforced with three types of superelastic shape memory alloy (SMA) rebars—NiTi, FeNCATB, and CuAlMn—in boundary zones. Three RC-coupled wall systems with four, eight, and twelve stories were selected as case studies. Afterward, Incremental Dynamic Analysis (IDA), was meticulously conducted to evaluate the structural performance under various levels of seismic excitation. Using the OpenSees program, the maximum critical values for the inter-story drift ratio (IDR) and the residual inter-story drift ratio (RIDR) were determined.

The results indicate a substantial reduction in RIDR when post-earthquake issues are considered. Among the three SMA types investigated, Cu-based SMA material exhibits the best performance in terms of RIDR reduction and restoration efficiency. Therefore, it is recommended to utilize Cu-based SMA materials in seismic-prone regions exposed to significant ground motions. This comprehensive analysis of the three materials contributes to a deeper understanding of the underlying mechanisms and benefits of SMA reinforcement in RC-coupled walls.
